Improvement in cushions for shuttle-boxes



UNITED STATES PATENT OFFICE SAMUEL Bo'oRN, oE LOWELL, MASSACHUSETTS.

IMPROVEMENT lN CUSHIONS FOR SHUTTLE-BOXES..

Specification forming part of Letters Patent No. 35,808, dated July 8,1862.-

To all whom, it may concern.-

Beit known that I, SAMUEL BOORN, of Lowell, in the county of MiddlesexandH State of Massachusetts, have invented a new and useful Improvementin Looms; and I do hereby declare the same to be fully described in thefollowing specication, and represented inthe accompanying drawings, ofwhich-- Figure 1 denotes a top view of a metallic case provided with myinvention, the same being applied to a race-rod of a loom. Fig. 2 is ahorizontal and longitudinal section of the same.

The nature 'of my invention consists in au improved cushion to be'applied to a metallic case, which is to be placed upon each end of therace-rod A of a loom, in order to receive the blows of the picker orpicker-staff, either in its extreme forward or rearward movements, andthereby prevent the injury usually arising to the picker or its staffwhen cstopped by a hard unyielding material. Y

The object of my invention is threefold: lirst, to prevent the violentconcussion and wear ot' the picker; second, to greatly diminish thenoise incident to the usual action ol'` the picker and picker-stati',and third, to preserve the cushion in its normal condition.

In carrying out my invention I employ one Vo r more disks,a,or otherpropershaped pieces a metallic case, B, and conne them together and inthe said case by means of a band or strap, d, passing around them inmanner as shown in Eig. 2. A cushion and its case, constructed as aboveset forth and as shown in the drawings, I apply to each end of theraceway and on the race-rod of the shuttle-box thereof, it beingconfined to the rod A by screws, or in any other suitable manner.

I have found by experience of more than a year that the combination ofleather, indiaw rubber, and hair, arranged as above set forth, mutuallyprotect each other against the violent shocks of the picker orpickerstaif, while at the same time they preserve such picker or stafffrom injury. A cushion, if made entirely of leather, soon becomesindurated and loses its elasticity. One of vulcanized rubber is liablesoon to become softened or injured by the oil on the picker-rod, andbesides, when inclosed in a metallic socket-,it is likely to Soon becomeso driven and compacted therein as to have its elasticity seriouslyimpaired,if notentirely destroyed. By placing in the rear of thecaoutchouc block a mass of .curled hair, and in front of it a cap 0rcovering of leather, I have found by experience that the caoutchouc ispreserved intact, or will not only maintain its elasticity, but will beprotected from thc softening and injurious effects ofthe oil.

I claim- My improved cushion, as made of a combination of leather,indiarubber, and curled hair, arranged within a metallic case, B, inmanner and for the purpose set forth.

SAMUEL BOORN.
